You can check on the bottle to see how many miles the oil you use is rated for, but most synthetic oils will be fine driving up to 7,500 miles without a change. Keep in mind that many oil manufacturers tend to underestimate how long their oil will last in order to keep you coming back for refills more often. Because of this it is generally safe to drive one to two thousand miles more on your engine oil than the bottle advertises.
